What is integration testing?

Integration testing is kind of black box testing done after Unit testing. The purpose of integration testing is to ensure distinct components of the application still work in accordance to customer requirements after integrating the units. Test cases are developed with the express purpose of exercising the interfaces between the components. Integration testing is considered complete, when actual results and expected results are either in line or differences are explainable/acceptable based on client input.
